Public Function New( _ 
   ByVal horizontalShift As Integer, _ 
   ByVal verticalShift As Integer, _ 
   ByVal backColor As RasterColor, _ 
   ByVal type As OffsetCommandType _ 
) 
- (instancetype)initWithHorizontalShift:(NSInteger)horizontalShift 
                          verticalShift:(NSInteger)verticalShift 
                              backColor:(LTRasterColor *)backColor

public OffsetCommand( 
   int horizontalShift,  
   int verticalShift,  
   RasterColor backColor,  
   OffsetCommandType type 
) 

Parameters

horizontalShift
Horizontal shift of the image, in pixels.

verticalShift
Vertical shift of the image, in pixels.

backColor
Fill color for the exposed areas.

type
Flags that indicate how to handle any exposed areas resulting from the image shift.

Example

Run the OffsetCommand on an image.
